Application filed September 2l. 1325. Serial No. 57,590.

This invention relates to means -for deinonstrating the effects ot diiierent colors `and combinations ot colors of artificial light on textiles of the different fibers and di'llerent colors in environments ot' diiierent colors.

An object ot the invention is to provide means for demonstrating the eiiect of artificial `light of diil'erent colors and combinations ot colors on textiles of different colors, ibers and weaves in environments of diierent colors, and thus atl'ord opportunity to yobserve and select the color, weave, and class of cloth most suitable for costumes on different types of individuals or for decorative uses, and to show the` cellula-r structure ot the tour fibers used in textiles; to display visually the eii'ect ot artilicial light on the chemical and physical properties ot fabrics including the weighting ot sillrs, dyeing, mercerization and linishing processes; to show the ei'i'ect ot "light on the tei;- ture ot materials in order to enable `one to observe the eiiect ot the diiierent materials and diiierent colors oi' materials lon different types of individuals; and generally to provide means tor observation of the eiiect ci artificial lights ot different colors. used selectively, or concurrently and interchange ably in series, such variations in the combinations ot colors being obtained optionally.

Other objects will appear trom the tollowing description, reference beingmade to the accompanying drawing illustrating an embodiment ot the invention in which Fig. 1 is a horizontal cross sectional view ot a stage 4or enclosure comprising theinventi-on. i

Fig. 2 is a front elevation with portions oit the opaque liront wall or curtain broken away.

Fig. 3 is a vertical front .to rear cross sectional view.

Fig. l is a reduced rear elevation.

In the embodiment of the invention shown there is yportable immature `stage or encl sure provided on one side `with means for supporting the textile or other materials which are to be subieetedto the ,effects Aof artificial lights ot 'diderent colorsfandlditferent combinations of col-ors which lights, in the :present instance, comprise electric lamps ot diderentgcolors controlled lectively oper' `ble Aindividual switchesyand selectively operable dimmer-s, spthat the dissent @dar and eeabirutoas .eff .faders perlmittingthe curtain l2 to be may be selectively used and the etllects thereof upon the fabrics may be observed.

The stage or enclosure comprises an opaque rear wall l provided with openings 2 having guides 3 tor receiving and supporting slides l having the sections 5 of textile or other flabricated materials upon which the effects of diilerent colors and combinations oic colors of artificial lights are to be observed. Ars shown, provision is made whereby textile materials composed respectively of the 'tour fibers used in teirtiles (cotton, sill, hemp and wool) may be simultaneously observed under the saine lights, to make clear their dii'lierent properties and .contrasts and the eiiects ot lights ot diiierent- `colors thereon. The forwardly extended divero'ing opaque side walls 6 have their vertical rear edges closely connected with the verticalside edges oi' the rear wall l so as to prevent all outside light from pass ingthrough such connection to the stage or enclosure. An opaque bottom wall or stage floor 7 and an opaque top wall S are con necteld to the upper ends oi" the rear wall and sidewalls in such a way as to prevent all outside light irom passing through such connection to the interior ot the stage or enclosure. A removable opaque iront `wall or curtain 9 has its edges closely contacting withthe edges `ot the top, bottom and side walls, respectively, and excludes all outside light from the interior ot the stage or enclosure, except such as may enter through an observation window or opening l which is surrounded by a trame il in and against which 4the tace oi the observer is pressed so as to exclude outside light vfrom the interior during observation of the effects of the various colors and combinations ot colors oi" artiiicial lights upon the material andthe environments.

A proper environment is obtained by a removable and replaceable curtain 12 having the color of; a part ot the surroundings in" which it is desired to observe the effects ot the artificial lights on the materials 5. The 4curtain Qissupported by a roller 13 raised and lowered to diierent 'adjustments tobbtain best results, as will be readily understOOd; by interchangeable vertically' adjustable curtains or draperies 14 selected to contornato the environment color to which the effects ef lights. #la essere te violelill) CII pared for purposes of selection of costume or decoration; and by a valance 15 of similarly selected color between the curtain 12 and the Jfront wall 9.

The electric lamps 16 are arranged in a transverse row in a .depression 17 between the .Front edge of theioor 7 and the wall 9 and have reflectors 18 arranged to project the light rays directly upon the material 5. The lamps 16 are in series, the lamps of each series comprising preferably a white, a red, a yellow and a blue lamp, the colors of the lamps of each series, as shown, being designated by letters `W, R, Y and B, respectively. Lamps ot different colors or tints may be used. rIhe circuit of each of the lampsl is controlled by an individual switch 19 of known construction, connection and operation so that the lights can be used individually or in any different combinations desired. This also permits one or more lamps from one or more of the series orp lamps to be used at one time so that any combination and relationship of colors from the series of lamps may be used.

VThe invention also comprises a series of spotlight lamps 20 and their reflectors 21 arranged adjacent to the series of lamps 16 and arranged to project the light rays thereof directly against the material 5 in the openings The lamps 20 comprise the colors white, red, yellow and blue, and are individually controllable by switches 22 of lrnown construction, application and operation, so that they may beused with the lamps 16 as above described, lor independently thereof as desired. .Y

Each series of lamps 16 is controlled by a dimmer device 23 otlrnown construction and application, whereby the brilliancy of illumination may be varied as desired.

The dimensionsy of the device and the relationship of the parts may be varied otherwise than as specifically mentioned without departure from the principle of the invention.' I do not restrict myself unnecessarily, but what l claim and desire to secure by Letters Patent is Y1; AV device or" the character described Vcomprising an Venclosure having opaque walls one of. which is provided with an opening and another of which walls is provided with an observation opening, means for supporting a section o'teXtile material across said first named openin T andl preventing outside lightfronij passing 'through the opening, a series of electric lamps of ,different colors within said" enclosure arranged to illuminate said tentile' naterial, switches control-V ling said lamps individually, and dimmers for said lamps. l
